<h1 id="二、环境搭建"><a href="#二、环境搭建" class="headerlink" title="二、环境搭建"></a>二、环境搭建</h1><p>Python扩展程序包的二进制文件下载网址为：</p>
<p><a target="_blank" rel="noopener" href="https://www.lfd.uci.edu/~gohlke/pythonlibs/">https://www.lfd.uci.edu/~gohlke/pythonlibs/</a></p>
<p><code>pygame</code> 是一个可以读取手柄和键盘模块，我的python环境为3.7版本所以我下载的的是<code>pygame‑2.0.1‑cp37‑cp37m‑win_amd64.whl</code>。</p>
<p><code>pyserial</code>是一个串口通信模块，我下载的为<code>pyserial‑3.5‑py3‑none‑any.whl</code>。</p>
<p>下载完成后以==管理员==的身份打开命令提示符使用 pip 指令安装：</p>
<figure class="highlight powershell"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><code class="hljs powershell"><span class="hljs-comment"># 跳转到文件下载的目录</span><br>C:\WINDOWS\system32&gt; <span class="hljs-built_in">cd</span> C:\Users\Administrator\Downloads<br><span class="hljs-comment"># 使用 pip 安装 文件</span><br>C:\Users\Administrator\Downloads&gt; pip install pygame‑<span class="hljs-number">2.0</span>.<span class="hljs-number">1</span>‑cp37‑cp37m‑win_amd64.whl<br></code></pre></td></tr></table></figure>

<p><code>pyserial</code>的啊安装也是一样的。</p>
<p>注意：如果是使用<code>pycharm</code> 编写的程序，会提示找不到模块，因为<code>pycharm</code> 运行环境的扩展库只扫描当前项目下的，因此我是使用VScode 编写。</p>
<h1 id="三、程序实现"><a href="#三、程序实现" class="headerlink" title="三、程序实现"></a>三、程序实现</h1><p> 定义通信规则：为了方便起见每次只发送一个字符，直行发送 ‘q’，加速发送 ‘s’，减速发送 ‘e’，左转发送 ‘l’，右转发送 ‘r’。</p>
<p>第一次调试可以打开<code>print(message)</code>查看系统获取的信息</p>
